求助！！！关于属性块炸开后的错误
我用cad2000作的属性块，在2004里炸开后，属性定义怎么会出现？？？？？？双击修改却发现它的显示为标记名称，并不是它的默认值。
下图左侧为炸开前，又为炸开后。
在线等！！！！！！！！！！！！

(princ) 请问怎么上传图片？ 1.新图形的字体没有设置中文字体，所以出现？？？号。
2.炸开后属性值会变成了属性定义，所以就会出现你说的对话框。
3.你可以不炸开图块来编辑其属性值，一样是用双击来编辑。 有些块是想炸开做局部修改的，有法避免那种麻烦吗？ 不用炸开，用refedit修改局部 炸开后属性值为什么会变成了属性定义？
请大侠解释一下！！！！
谢谢！！！ 不要用炸開命令， 用burst命令就ＯＫ． 呵呵 burst 未知命令？？？？？？ 请教BDYCAD老兄！
burst 是未知命令 属性本来就是一个同一个块定义下可以更改多个特性的块。属性在未被定义成块前是一个属性标记，其中包含了属性的各项预设特性和值。当属性被定义成块之后，就自动继承之前的那些预设特性和值成为一个块，你可以非常方便的在不改变块定义的状态下变更这个属性块的各项特性。你把一个单行文字定义成块，你必须去块编辑器中才能变更文字内容，而且一旦改变所有的块定义都会改变。而属性定义成块，只要直接双击就能改，而且改的只是当前的这个块。
